CICADELLINAE: PART 2. NEW WORLD CICADELLINI 585 
A number of accounts have been published indicating that several species of 
Carneocephala are common on Bermuda grass. Others have been reported on 
other grasses and on sugar cane. Carneocephala flaviceps (Riley) is one of the 
commonest leafhopper species occurring at light in the Coastal Plain of North 
Carolina, and probably is of economic importance in this area, as it has been 
reported to be in the West Indies. Mason and Yonke (1971b:113) listed the 
plants from which flaviceps has been collected. Three species have been found 
to transmit the pathogen of Pierce’s disease which affects grapes and alfalfa 
(Nielson, 1968c:108-116). C. floridana (Ball) was collected by Ball on 
chenopodiaceous plants in southeastern Florida.

Ficures 478-480 
Tylozygus Fieber, 1866a:501. Type-species: Tettigonia nigrolineata Herrich-Schaffer, which 
is a synonym of Tettigonia bifida Say, by monotypy. 
Length of male 4.0-5.2 mm, of female 4.8-6.0 mm. 
Head slightly to moderately produced, median length varying from three- 
tenths to two-thirds interocular width and from one-fourth to one-third trans- 
ocular width, anterior margin broadly rounded in dorsal view, without a 
carina at transition from crown to face, ocelli located on or before a line be- 
tween anterior eye angles, each equidistant from median line of crown and 
adjacent anterior eye angle or slightly closer to latter, crown convex without a 
concavity across ocelli, surface irregularly punctate; antennal ledges not 
protuberant in dorsal view, not carinate, in lateral view with anterior margins 
rectilinear, or concave and vertical or slightly oblique, clypeus convex, 
granulate medially, not or scarcely flattened medially, muscle impressions not 
very distinct, transclypeal suture entire or obsolete medially, other head 
characters as in Ciminius Metcalf and Bruner. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae not complete; posterior 
margin slightly convex or slightly concave, disk not sculptured, without 
pubescence; scutellum not transversely rugulose behind transverse sulcus.
